If you can get hold of a Davis data logger (either usb or serial) you can
supposedly get it to interface with weewx according to some stuff I've stumbled
on by searching a weewx user group.  From there you can get weewx to
create a "wxnow.txt" file, from which you can create a fake weather server
that Xastir can read from using the "wxnowsrv.pl" script in our scripts 
directory.  That script periodically polls the wxnow.pl file and produces
the same sort of network stream that either the Davis or LaCrosse daemons
in Xastir do (those programs pull data out of a database that is populated
some other way, by meteo in the davis case and via open2300 for lacrosse).

I cannot, however, help you with getting it to work with weewx.  You might 
start here:  https://groups.google.com/g/weewx-user/c/NWZe-I-wYWA/m/WYnfM1tVCAAJ
It might be difficult, I cannot say, as I have neither a Davis nor weewx.

Davis used to make a device called an "APRS data logger" that would output
correct APRS weather data payloads, and if you had one of those Xastir knows
how to use it (or at least it did once, when I hacked in the capability for
a local owner of that device).  I believe this device is long discontinued.
